People love to be self-righteous. the world is just that way. It's mean spirited to attack someone who is down already. It says volumes about that person's character. I know that the pain caused from those kinds of attacks cannot be shaken off very easily. It takes a couple of days to get over the shock.
Dealing with life as a depressive is a constant struggle. Just doing ones daily activities takes so much energy. I feel for you because I've been there.
I hope you are getting help. It's so difficult to deal with depression all alone. I'm sure you have seen many posts dealing with this so I won't preach.
I hope you find some relief and can move past this difficult experience.
